Seeing this I start thinking:
- very little open water on the whole hemisphere.
- maybe there's an ocean on the other side?
- where else would the evaporation for rain come from?
- but then there'd be less green in the center of the continent where moist sea air doesn't reach.
- and there's gotta be some rain or there wouldn't be that many plants.
- oh, wait. Mist forests in the higher reaches of (sub)tropicals...
- hmm, a whole world shrouded in mist lingering between all the plant life? Interesting...
...and so on.
Your work inspires, so it's a good one!

Good comment. I was not thinking that far. A fully green planet feels fresh idea.

Happy to help, I guess?
A fully green planet seems very scifi to me. "Normal" geology doesn't really allow too many plants without a large(ish) source of open water somewhere nearby.
At least as far as we know from our small pool of samples.
If there's no open water, there'll be very little evaporation from sunlight on water.
Less evaporation leads to less rain.
Less rain means less water is carried into the land.
Less water inlands means fewer plants because plants need a certain temperature, water and fertile soil to grow.
Less plants then means less green inland, which in turn leads to more open area where sunlight might hitΒ pools/seas/oceans of water which leads to more evaporation and so on...
And all that gets screwed when you add artificial irrigation systems or a civilization that's actively growing these plants.
Heck, maybe the catch-all, do-all of nanites that carry water and nutrients to the plants that are too far from the coast to receive their moisture from rain...

True. What happens, if the planet would be a series of small lakes, or seas. Would it work? What planet would seem then?

I'd guess everything above 50% open water surface should work in creating a green world.
If it's concentrated in one big ocean you'll have green shores and some hundred km into the land that get the rain, if it's smaller lakes scattered about you'll get thinner green belts around the lakes but more of them, which will combine to a vast green carpet.
I think I have some simple program around here that can simulate a very rough/light version of vegetation growth in accordance to available water.
There'll be other factors influencing the system like distance to the sun (is the world closer and thus hotter which makes evaporation easier? Or further out and thus colder with less evaporation?) and atmospheric composition.
That's what is making painting a realistic world hard. But your work looks great, I especially like the lights, so there's no need to change it
